Hardware

Architecture

The NEC Nehalem Cluster platform consists of several frontend nodes for interactive access (for access details see Access) and several compute nodes for execution of parallel programs.


Compute node CPU architecture types installed:

  • Intel Xeon 5560 (nehalem)
  • Nvidia Tesla S870 GPU


Features

  • Operating System: ScientificLinux 5.3 on Intel based nodes
  • Batchsystem: Torque/Maui/Moab
  • node-node interconnect: Infiniband + GigE
  • Global Disk 60 TB (lustre)
  • OpenMPI
  • Compiler: Intel, GCC, Java
